No, the only mirrors provided by RPI would be found in the bathrooms. You should look into buying a full length (or really, any size) mirror for your room. I believe I got one for $5 at Target last year.
I personally have tons of clothes. While there is a considerable amount of space for them, I can’t bring them all to school. The armoires should measure about 39” across the hanging rod. If you have tons of shoes, consider buying a shoe storage container. Remember, also, that you can buy storage things when you move in. It’s smarter to know what exactly you’re working with before you make the purchases.
